He is also a member of the American College of Dentists and International Congress of Oral Implantologists.

Naval Service
After graduation, Dr. Laizure was stationed in Hawaii to serve four years in the Navy.

Professional Experience
Dr. Laizure has provided exceptional dental care for his patients for over 35 years and has enjoyed this time by giving back to the Walla Walla area through numerous civic and nonprofit organizations.

It is important to Dr. Laizure to keep up to date on continuing education classes and the latest advancements in dental research. He is also a clinical instructor at the world-renowned Kois Center and has advanced training in dental implants, aesthetics and restorative dentistry.

Dr. Laizure’s attention to detail is extraordinary, enabling him to deliver gorgeous smiles that fit the individual styles and desires of his patients.

In his book “Saving My Library: Nine Lessons Preserved From the Fires of Time,” Dr. Laizure compiles his life experiences as a leader. This book will teach you important lessons, no matter your age, including:

  • Promoting self-esteem in others
  • Understanding the value of interdependence
  • The importance and significance of generosity
  • How every day is a day to be lived to the fullest

“I so admire someone who not only endured many challenges in life, but learned from the experiences and is willing to share those nuggets of wisdom. Saving My Library is more than just a self-help book. It’s inspirational, entertaining, and full of helpful tips.” – Shanna Hatfield

Dr. Laizure loves “fellowship in the outdoors” — spending time afield with good people whose companionship he values. This is exactly what Dr. Laizure appreciates most during his free time. You will often find him jetting off to Mexico for fishing excursions, hiking into the Blue Mountains during the fall hunting season or exploring the beauty of the American West.

Sam Castillo, DMD

Dr. Sam, a native of New Mexico, did his undergraduate studies at the University of New Mexico. In 1974, Dr. Sam applied and was accepted to the University of Oregon Health Science Center School of Dentistry. It was there that Dr. Sam met Dr. Laizure.

Upon graduation from dental school, Dr. Sam enlisted in the United States Navy as a dental officer and was stationed at Sand Point Naval Air Station. Three years later, upon completion of his military obligation, Dr. Sam opened his dental practice in the town of Duvall, Washington. Dr. Sam was the first dentist in that small town — you might say that he was a pioneer. The small town needed a good dentist who could provide the care they needed.

During his life as a dentist, Dr. Sam developed an interest in the art of winemaking. Little did he know that this hobby would become his retirement lifestyle. After 35 years of dentistry, Dr. Sam sold his practice, and he and his wife, Deborah, moved to Walla Walla, where his winery is located. Dr. Sam spends the majority of his time working at the winery. When he is not there, he is here practicing dentistry with Dr. Laizure.

Dr. Sam comes to Walla Walla Dental Care with vast experience in all aspects of dentistry. He is well versed in cosmetic dentistry, implantology (i.e., dental implants), endodontics, crowns, bridges, removable dentures and orthodontics.

In the dental field, Dr. Sam has undergone extensive training in the field of orthodontics. Creating long-lasting, beautiful smiles through orthodontics is a very rewarding treatment for his patients. Being able to offer this to our patients makes Walla Walla Dental Care an excellent place for complete and comprehensive dentistry.
